Need lighting advice from my fellow reefers...

[bulletsworld]

I'm trying to decide on whether to buy a used lighting unit. Need your advice to tell me what you think, if good deal, pro's and con's. As it would be my first MH unit, pretty silly hey. Well pick a way and convince me to go with it or not to go with it. I would love to hear all your advice. Since all I can think of is how much better my tank will look and how my pods, fish and anemone will love me if I flourish them with the closest thing to real live SUNNNNNNN!



My tank is 48"L X 16"W X 20" H (Tank is a 77 gal)

Used Lighting system is:
Hamilton 2 x 175W 10, 000k MH & 2x 40W power compact blue actinics.
Dimensions of fixture: 48inch length X 13inch width X 6inch height
it's got 1 fan on one side, and a filtering thin sponge thingy on the
other for trapping dust and what not
- one metal halide ballast (magnetic I believe) and the dimensions are:
15inch length X 7inch width X 4inch height
- one power compact ballast (also magnetic I think)
- the fixture is black aluminum with high quality electro-white reflector
and UV filtering acrilic lens
- the lights are about 7-8 months old, so you may need to replace.
Asking $400 on this fixture.

Help! Need your thoughts reefers!
